Structural Repair

Uneven, sloping, or bouncy floors

Slanted or bouncy floors indicate your internal supports are failing, often causing the subfloor to separate visibly from your baseboards.

What causes uneven, sloping, or bouncy floors?

Section diagram

Your floors are only as stable as what stands directly below them. When cimentation piers sink into the soil or moisture actively destroys the structural integrity of your crawl space wood framing, the floor loses its flat plane and drops.

Root causes 3 most common

If floor joists are spaced too far apart or have been weakened by high humidity and wood rot, they bend under the house's regular weight, creating bouncy floors.

Internal concrete columns or blocks shifting into weak, shifting clay subsoils drop the central beam of the house, pulling the middle of your floors downward.

When the soil beneath a concrete floor slab washes away or shrinks, the heavy slab cracks and drops, leading to severely sloped tiles or hardwood.
